It is extremely important to keep your pool safe to use, and this means killing micro-organisms that may be harmful to your health. It is also desirable to keep your pool water looking clear and fresh, and remove algae which can turn the water an unsightly green colour. There are various methods of sanisiting your pool:

Chemicals - The most popular chemical for pool sanitisation is chlorine, which is easily available and inexpensive. Alternatives are available, such as bromine. We also supply algaecides for reducing the level of algae in your pool, and flocculants and clarifiers to help keep your pool water fresh and clear. 

Mineral & Chlorine Purifiers - These systems ultilise automatically released minerals and chlorine to safely neutralise micro-organisms and provide cleaner, clearer, and softer water.

Salt Chlorinators - For salt water pools, these systems generate chlorine from dissolved salt in the water, which effectively neutralise micro-organisms.

Ionic Purifiers - These systems create and release copper and metal ions into the pool water, which attack and neutralise micro-organisms. Due to the presence of copper, they are also effective algaecides.

Ozone & UV Purifiers - These systems utilise self-produced ozone and Ultra Violet (UV) light to attack and neutralise micro-organisms. Ozone purification can help provide a clearer pool by dissolving grease and oils. Both methods are ideal for neutralising micro-organisms that are resistant to chemicals.  

Chemical Concentration

You should always use the correct quantities of chemicals for your pool size. To work out the water capacity of your pool (in gallons), you can use the following formulas:

Imperial (gallons):

For square or rectangular pools - length (ft) x width (ft) x average depth (ft) x 6.25 = volume (gallons)
For circular pools - 3.1428 x radius2 (ft) x average depth (ft) x 6.25 = volume (gallons)

Metric (m3):

For square or rectangular pools - length (m) x width (m) x average depth (m) = volume (m3)
For circular pools - 3.1428 x radius2 (m) x average depth (m) = volume (m3)
Test kits are available on request.

Pool pH

All pools should have a pH between 7.2 and 7.6. A low pH is acidic and corrosive, and will damage pool parts and sting bather's eyes. A high pH is alkaline and stops any chlorine present working as well as being scale forming.

Test the pH of your pool using Phenol Red in a test kit. If your pool pH is not within the required limits (either too high or too low), you can add a pH minus or a pH plus to bring levels within the required limits.

pH minus - A pH above 7.6 ('high') is lowered by adding pH minus (sodium bisulphate or pool acid)
pH plus - A pH below 7.2 ('low') is raised by adding pH plus (sodium carbonate or pool alkali)
Test kits are available on request.
